3.4A4 - Spring Vibration Isolators

A4 series mounts provide excellent isolation from critical vibrations and efficiently protect structures from transferring vibrations. Model A4-100 has 1" deflection while A4-140 has 2" deflection.

Recommended for:

Air conditioning equipment, compressors, air handling units, centrifugal fans, pumps, chillers, and applications where low-frequency isolation is required.

Features:
Rubber pads on the inside of housing prevent metal to metal contact.
Spring elements are color coded.
Maximum leveling adjustment 1/2" for all mounts.
Top cast leveling plate slides inside cast iron housing, which provides extra stability in all directions when horizontal forces applied.
These mounts are available in two assemblies: hexagon head screw top and flat rubber top.
Safety factor will accomodate 50% extra load from maximum load.
